Commercial

Atlas Construction Group is qualified in the application of all major commercial roofing systems. If you're in the process of constructing a new building, or planning the replacement of an outdated roof on an existing building, in addition to what has been the standard in commercial roofing for decades, (Built Up Roofing, Modified and Metal) there are five alternative types of commercial roofing systems to consider and increasing in popularity: Duro-Last, Thermoplastic Roofing Systems (TPO), Ethylene Propylene Diene Monomer (EPDM), Photovoltaic Panels and lastly, Green Roofing Systems.

The Old Standard:

Built-Up Roofing
Built-Up Roofing is one of the oldest and most reliable methods for installing a new roof, and it's also one of the most economical roofing methods available today.
Built-Up Roofing (or B.U.R. as it is sometimes called) is made by layering several plies of roof felts (strength) with bitumen (waterproofing) in between, creating a laminating effect. The layers of bitumen and alternating roof felts (made of bitumen-saturated Fiberglass, polyester, other fabrics) combine to form a watertight barrier that exhibits exceptional heat-resistance, as well as opposition to extreme wind. Built-Up Roofs are ideal for flat or nearly flat surfaces, and can be installed over most roof decks, provided the proper substrates are being used.
That includes wood (with a rosin sheet and base sheet needed first), steel (a minimum of 22 gauge), structural concrete, and cement fiber (with a base sheet or mechanically-attached insulation). BUR roof systems can be used with all the available roof insulation in any thickness to provide exceptional energy efficiency and long term waterproofing.
Built-Up Roofs vary with regard to service life, depending on geography, foot traffic, materials and number of plies used, but can last up to 25 to 30 years under ideal conditions. That makes them one of the most economical roofing methods available, when compared to other methods on a cost-per-year basis.
Modified Bitumen Roofing
When choosing a roofing material, it is always a good idea to pick one with a proven track record. Modified bitumen roofing materials have been around since the mid-'60s, but it took until the mid-'70s for its use to dominate the industry. Now modified bitumen roofing materials are the most widely used on flat roof commercial buildings.
Modified bitumen roofing materials come with a variety of instillation specifications from torch down to cold applied processes. The newest innovation in modified bitumen roofing materials is a self-adhering strip for installation. The roofing materials are rolled out and stuck together with the self-adhering strip that does not require special tools or added labors.
Once the material is rolled out and the adhesive strip bonds with the substrate, the roof has all of the water protection qualities of the other methods of modified bitumen roofing instillation techniques.
The great thing about modified bitumen roofing is the large assortment of material and surfacing options. The two most commonly used materials are asphalt based, with one of them having a rubberized asphalt blend for increased flexibility. Surface options include several different types of gravel coverings, as well as factory-applied cool roof coatings that are Energy Star compliant.
Some types of modified bitumen roofing with Energy Star compliant coatings have the added benefit of saving a consumer up to 50% on their utility costs. Modified bitumen roofing with cool roof coatings reflect solar heat away from the interior of the building to help cut the energy costs associated with warmer climates.
When considering modified bitumen roofing materials, many people manage to save thousands on their project when using Energy Star compliant materials. And these savings are not just limited to utility costs; there are also several different tax credits available as well.

Metal Roofing

Atlas offers both exposed fastener and concealed fastener metal roofing systems. As the name implies, exposed fastener metal roofing systems use screw fasteners that are visible on the exterior of the roof surface after installation. These exposed fastener metal roofing products are economical, have been in service for decades, and are extremely popular in a wide variety of metal roofing applications.
In concealed fastener metal roofing systems such as standing seam panels, the screws are completely concealed and protected by the roof surface. Certain metal roofing systems are manufactured with standing seam panels that produce very clean, aesthetically pleasing lines.
This type of metal roofing system also exhibits the very best in weather resistance and durability since the fasteners are not exposed to the outside elements. We offer the three primary types of standing seam metal roofing systems; screw flange, snap lock, and mechanically seamed. Each of these metal roofing system designs uses a slightly different method to secure the panel to the metal roof.
In addition, recent innovations in metal roofing paint systems and coating technology have significantly enhanced performance. The vast majority of today's metal roofs use a Galvalume coated steel substrate which virtually eliminates worries about rust and corrosion. These paint systems use cutting edge technology and inorganic pigments to provide the maximum protection against harmful UV rays.
Secondly, metal roofing is tough. When it comes to wind and weather resistance, metal roofing stands alone. Union's metal roofing meets the toughest wind, fire, and impact codes in the country. Your metal roof will probably outlast you. Most metal roofs last 3 to 4 times longer than an asphalt shingle roof.
Thirdly, there is a genuine concern in helping to maintain and improve the environment for future generations. In this regard, metal roofing meets the criteria of recycled content, recyclability, and energy efficiency. Metal roofing is one of the most energy efficient roofing systems available and tests have shown that it can save you up to 40% on cooling costs.
In addition, it's not asphalt based like shingles, which means its production doesn't continue to fuel our country's biggest addiction… oil. Although these are the major drivers, there are many other reasons why metal roofing is gaining in popularity.
Duro-Last Roofing System
Duro-Last, Inc. is the pioneer and one of the nation's largest manufacturers of custom prefabricated roofing systems. Every Duro-Last roofing system is prefabricated in one of four Duro-Last manufacturing plants to meet your specific roofing needs. Approximately 80% of the field seams and roughly 95% of the remaining critical areas (projections and perimeters) are welded under ideal factory conditions. The result is a consistent, high quality roofing system designed and manufactured for each building on which it's installed; a concept that renders other roofing systems obsolete. The Duro-Last single-ply membrane outperforms other roofing products in all critical areas.
Prefabricated
Every Duro-Last single-ply roof is measured and manufactured to exact size, accommodating every rooftop penetration. Prefabricating the vinyl roof membrane in our controlled factory environment eliminates up to 85% of seaming that is done on-site during rooftop installation, and improves the long-term performance of the roofing system as well reduces the material waste associated with the installation of most rolled systems. This precise attention to detail ensures an excellent fit and delivers worry-free, leak-proof protection. Duro-Last can even assist your architect, facilities or maintenance personnel in developing specifications for your roofing project.
Durable
The Duro-Last roofing system, made from a PVC membrane, is resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes. Duro-Last's custom flashing components - made from the same vinyl roof membrane as our deck material - resist ponding water and help solve roof problems before they can occur. Plus with Duro-Last's available Roof-Trak® Protective Walkway System, heavy equipment and maintenance traffic are easily managed.
Installed With No Disruptions
Building occupants will hardly know a new roof is being applied, because installation is quiet and safe. Our PVC roof membrane is mechanically-attached to the deck; edges and vinyl roof components are heat-welded together to complete the watertight, monolithic roofing system installation. There are no loud machines, no hazardous materials, no noxious fumes, no hot tar, and no mess. Because it's made from lightweight vinyl, a new Duro-Last roofing system can often be installed over an existing roof without an expensive tear-off, virtually eliminating dust or falling debris that could interfere with building activities or damage sensitive equipment.
Energy-Efficient

Thermoplastic Roofing

TPO roofing systems are among the fastest growing commercial roofing systems. Made of an especially durable material with a low-temperature flexibility and a high-temperature tolerance, these roofs are exceptionally resistant to ultraviolet, ozone and chemical exposure. TPO roofs can be expected to have a lifespan of 20+ years, and also feature a high resistance to fire, punctures, chemicals and high winds.
Advantages of Thermoplastic Membrane Roofing
There are a variety of factors to consider when choosing a new roofing system for your home or business. Aside from the immediate costs, there's the current roofing system on the building, the building design, future maintenance costs, ease of repair and durability to name a few.
In a head-to- head comparison, thermoplastic membrane roofing boasts numerous advantages over other roofing systems for commercial and residential use. In addition to being naturally UV and heat resistant, a TPO roof also remains flexible as it ages - all of which significantly increases its expected lifespan. Atlas Construction Group can ensure that its TPO roofing will provide unparalleled quality, resulting in low maintenance.
Check out these additional advantages of thermoplastic membrane roofing:

Resistant to a wide variety of chemicals

Environmentally friendly and recyclable

White TPO roofing can provide significant savings in energy costs

Maintenance is fairly minimal and easy

EPDM Roofing

EPDM roofing offers superior durability and versatility, making it one of the longest lasting types of commercial roofs available. EPDM commercial roofing systems are also typically easier to install, maintain and repair than most other types of commercial roofs.EPDM Roofing BasicsEPDM roofing is short for Ethylene Propylene Diene Monomer roofing - otherwise known as rubber roofing. An EPDM roof is a single-ply membrane, meaning there is only one layer of roofing material. EPDM thickness ranges from 30 mils to 100 mils, with the most common thickness being 45 or 60 mils.
Relatively inexpensive, EPDM roofing has been common in the U.S. since the 60's, and is one of the most frequently used types of roofing materials for a low-slope or flat roof. EPDM roofing also features enhanced durability and versatility, and is typically considered easier to install, maintain and repair than most other types of roofing materials. Rubber roofing can give your company or home an inexpensive option when considering roof installations.
EPDM Membrane Roof Installation
There are 3 standard procedures for EPDM membrane roof installation. First, there is fully-adhered membrane, which uses water or solvent-based adhesives to adhere the membrane to the roof base.
Next, there is mechanically-fastened membrane, which is attached by mechanical means to the roof base.
Finally, there is loose-laid membrane, for which installation requires that the membrane be secured to the roof base only at the perimeters or any point of penetration. Atlas Construction Group's EPDM roofing ensures both quick and efficient installation and superb quality.
Typically, round river rock or concrete pavers are used during EPDM membrane roof installation to hold the materials in place. During installation, river rock is usually applied at a rate of 1,000 to 1,200 pounds per roof square. Pavers used for rubber roofing generally weigh about 20 pounds per square foot.

Photovoltaic Panels

As energy costs continue to rise and America looks towards green and sustainable energy, many building owners are turning to solar energy roofing systems. PV solar panels installed over a rooftop or used with glass, membrane and roof-mounted tile, absorb sunlight and convert it to energy that can be used to power a building. Although not in wide use, PV panel roofs offer great potential to conserve energy and control skyrocketing costs.
PV Panel Roofing ExplainedPhotovoltaic Solar Panel Features
A photovoltaic solar panel is typically rigid and rectangular in shape, ranging in size from 2' by 4' to 4' by 8'. There are however, some flexible PV panel systems that are as large as 2' by 20' or more. Rigid solar PV panels usually have a glass cover, whereas their flexible counterparts feature a durable film cover. Both rigid and flexible solar roofs are designed to withstand harsh weather conditions including storm and hail damage, and are obviously resistant to deterioration from UV rays. Solar photovoltaic roofing will create power for your home or business for many years.
The excess power that your roofing creates can be sold to utility companies and actually create profit for your business.
Types of Photovoltaic Roof Systems
There are two main types of photovoltaic roof systems on the market. Solar PV panels, described above, are the most commonly used systems for solar energy roofing. Solar thermal collectors, on the other hand, convert sunlight into thermal energy instead of electricity. The primary purpose of solar thermal collectors is to heat water. These systems are often installed on a roof alongside PV panels for optimum, whole-building energy capture.

Green Roofs

Perhaps of all the types of commercial roofs available today, green roofing systems have experienced the greatest surge in popularity in the last few years. Sedum green roofs are typically flat roofs that are partially or completely covered with vegetation and soil and planted over a waterproofing membrane. Green roofing systems reduce the urban heat island effect by soaking up heat and also are found to dramatically improve a roof's insulation value - lengthening the lifespan of the roof by as much as two to three times longer and saving on heating and cooling costs.
Why Install Green Roof Systems?
The motivation for installing green roof systems is varied, as they offer plenty of benefits over traditional roofing. For some, green roofing is a necessary step on the path to LEED certification. Some cultivate green roof systems simply out of a desire to be environmentally responsible. Plenty of others are looking for ways to conserve on energy as a means of reducing costs. Whatever the reason, the construction of all green roof systems follows the same basic blueprint. The key components of include decking, waterproofing, insulation, drainage, filter cloth, medium and, finally, plants.
The selection of plants depends entirely on the roof's primary purpose, but ultimately comes down to a question of how much time and money you have to allocate to roof maintenance. Green roofing can help your company or home save money by saving you countless dollars on energy costs and even providing revenue through the sale of excess energy.
Green Roofs, LEED & Responsible Building
Green roofs, LEED certified construction, and other environmentally responsible building practices are on the rise. Awareness campaigns extolling the virtues and benefits of sustainable building and design are encouraging municipalities across the country to follow the example of cities like Chicago, which currently leads the nation in green roofs, LEED certification and incentives to encourage environmentally responsible businesses.
